Lankinen made 21 saves on 22 shots in relief in a 2-1 win over Toronto on Saturday.
Thatcher Demko (undisclosed) left the game midway through the first period, and Lankinen stepped into the blue paint and excelled. Lankinen was especially great late, making a sprawling glove save on Auston Matthews on a power play with under two minutes to play to preserve the lead and win. Lankinen's success this season has given him a role for Team Finland at the 4 Nations Face-Off, which starts Wednesday. He's 19-8-7 with a 2.53 GAA and .905 save percentage heading into the tourney. There is no information on Demko's injury or potential absence.
